Please check out the upgrades below and don't forget camshafts, lifters and other components!

Note: These kits are not balanced assemblies, balancing is strongly recommended for maximum performance and engine longevity.  Also, these Forged I Beam Rods may require clearance work.  Check out the upgrade section below for cap screw style Connecting Rods that rarely have issues with clearance. Money well spent!

A quick note about the crankshaft upgrade below.... The aero-winged crankshaft will increase horsepower by reducing windage.  It has lightened holes in all rod throws and has straight shot oil holes. Another great product from Scat and Northern Auto Parts!
